Providing tailored electrical power solutions to the African market has positioned Trafo Power Solutions as a key player in the region. Its success is rooted in its expertise, extensive experience and thorough understanding of the needs of mining operations across the continent. The company has the capabilities to meet the specific challenges associated with electrical power supply in these harsh and demanding environments.
Trafo Power Solutions has provided nine transformers to a mineral sands operation in Mozambique; seven were skid-mounted so they can be easily repositioned on site as needed.
One of Trafo Power Solutions’ latest projects highlights its ability to provide specialised transformer solutions to meet the rigorous conditions of mining applications. It recently supplied nine transformers to an electrical contractor for installation at a mineral sands operation in Mozambique.
The delivery includes seven 800 kVA transformers designed for skid mounting, to enable easy mobility across the expansive mining site. The other two units, rated at 160 kVA, will be pole-mounted. All transformers in this order are rated at 22 kV to 415 V, aligning with the site’s specific voltage requirements.
David Claassen, Managing Director of Trafo Power Solutions, explains that this latest order follows a previous successful supply of four dry-type transformers directly to the mining operation. The earlier batch included 3 150 kVA transformers, also rated at 22 kV to 415 V, and installed within IP23 enclosures. The transformers were equipped with the necessary control and protection equipment to ensure robust performance in the highly corrosive operating environment of the mineral sands mine.
“The mineral sands mining environment is particularly harsh, with high humidity and salinity levels that can accelerate corrosion. Our transformers are specifically designed to withstand these conditions, providing longevity and reliability in such an aggressive setting,” says Claassen.
A key factor in this repeat business was the mine’s confidence in the performance of the previously supplied transformers. “When the need arose for additional transformers, the customer specifically requested Trafo Power Solutions, which reflects our commitment to delivering quality solutions that meet the exact needs of mining operations,” Claassen adds.
Among the critical design considerations for the transformers was the need to minimise electrical losses and ensure the ability to handle large non-linear loads from the mine’s variable speed drives (VSDs). The transformers were engineered according to SANS 780 Edition 5.1 standards to achieve the lowest possible losses. Additionally, due to the site’s known voltage supply instability, the transformers were designed to withstand fluctuations while maintaining consistent and reliable power.
Aside from the technical specifications, the project also posed significant logistical challenges. The remote location of the mine required careful logistical planning for the transportation and installation of the transformers. “Logistics is always a key factor when supplying equipment to mining operations in remote areas. We worked closely with our partners to ensure a smooth delivery process despite the challenges,” says Claassen.
Further reinforcing its relationship with the electrical contractor and the mine, Trafo Power Solutions has secured an additional order for 18 transformers, which are scheduled for delivery by the third quarter this year. This ongoing partnership confirms the company’s reputation as a trusted supplier of high-quality purpose-built transformers tailored for mining applications in Africa.
As Trafo Power Solutions continues to expand its presence across the continent, its commitment to delivering reliable, durable and efficient electrical power solutions remains at the forefront of its strategy. With a strong focus on engineering excellence and a deep understanding of mining conditions, the company is well-positioned to support the sector’s evolving power infrastructure needs.
